UNITED STATES ROBERT BUTLER, 0F BOSTON ,MASSACHUSETTS TOBACCO PIPE.`

Application led April 28, 1925. f Serial No. 26,508.

To all lwhom t may concern:

Be it known that I, ROBERT BUTLER, a citizen of the United States, residing at Boston, county of Suffolk, State of Massachusetts, have invented a certain new and useful Improvement in Tobacco Pipes, of which the following is a specification, reference being had therein to the accompanying drawings.

The i-nvention relates to a new and useful improvement in tobacco pipes. The object of the invention to provide a tobacco pipe in which the tobacco will burn down evenly in the bowl, the clogging of the smoke passages will be lessened, and outside air will be drawn in to mix with the smoke to condense vapors from the burning tobacco thereby lessening the entrance of the same into the mouth of the smoker. One feature of the invention consists in providing a mouthpiece having in addition to the smoke passage therein a passage into which a tube is inserted to communicate with the outside air. Another feature consists in providing a condensingchamber having an air-cooled tube passing within the chamber and thereby forming a condensing member thereof. Another feature consistsin providing a tubular member placed in the stem portion of the4 pipe 'so that one end thereof shall communicate with the fire chamber in the bowl, and the other end with the outside air through a passage in the mouthpiece, said tube passing within and through said condensing chamber and communicating therewith through a port that divides said tube into a smoke passage and an' air passage, said air-cooled portion of said tube thereby forming the internal condensing member of the said condensing chamber. Other features of the invention will be set forth hereinafter.

The invention will be fully understood from' the following description when taken in connection with the accompanying drawings and the novel features thereof1 will be pointed out and clearly defined in the claims at the close of this specification.

In the drawings:

Fig. 1 is a longitudinal section of a pipe embodying the invention.

Fig. 2 is a section on line 2-2, Fig. 1.

Fig. 3 is a detail view, in side elevation. of the tubular member.

Fig. 4 is a bottom plan of the tube, Fig. 8.

Referring now to the drawings:

fitted. 9 is a -fire chamber in the bou/1,10

and l1 are ports in the tube 8, 12 the smoke passage in the mouthpiece,and 13 an air port for passage 7 or for tube 8.

`Preferably the shell-like member 4 is `of thin metal but may be ofany other/suitable material, and preferably it is separable' from the stem 2but may be fastened to or be a part thereof. l

.Preferably the mouthpiece 3 fits into. and is separable from the shell 4 but may be fastened to or form said sleeve.

' Preferably the tube 8 is of thin metal but maybe ofvany other suitable material, and preferably it is separable from the stem 2 and the mouthpiece 3 but may be fastened to or be a part of either. When assembled, I

tube 8 extends across thelower portion or bottom of the fire chamber 9, through the passage 6 of the stem 2, within and through the condensing chamber 5, and into or` through' the passage 7 of the mouthpiece 8. Tube 8` communicates with the `outside air through the port 13, with the condensing chamber 5 through the port ll, and with the fire chamber 9 through the port lO.

Port 10 is preferably placed on the under side of the tube 8 to allow the drip to clear from the tube and to prevent the clogging of the port by the tobacco from afbove. Port l0 is-extendedwell into' the wall of the tube 8 so4 that suction action will be distributed over the bottom :of the fire chamber 9 thereby causing the smoke to spread and divideV to enter the tube and thereby causing the tobacco to burn down evenly in the bowl of the pipe.

Port 11 divides thetube 8 into a smoke passage and an -air passage and determines their relative lengths. Port l1 is preferably placed on the under side of the tube 8 to allo-w the drip to clear from the tube and to fall into the condensing chamber 5. Port 11 is preferably located near the stem 2 of the bowl so as to extend the cold-air portion of the tube 8 as far into the condensing chamber 5 as may be possible thereby 'forming an internal condensing member for said condensing chamber. It is because of port 11 that air and smoke are forced to rcome together' within the tube 8 and mix ibetore passing from the tube.

When the pipe is in action, smoke is drawn into the tube 8 through .the port 10 and ,air is drawn into said tube through the port 13 and the smoke and air come together within the tube. The mixture then passes k.through the port 11 and .enters the condensing .chamber 5 thence through said Condensing chamber and the passage 12 .in the mouthpiece vto enter themouth of thesmokcr.

The condensing chamber 5 is `cooled externally through the :thin-:walled sleeve 4. ythat encloses said .chamber .and is cooled internally yby tlie`gair-eooled portion of the tube 8 that extends within said chamber ,and forms a condensing member thereof zand .also by the air that enters said chamber through said port 11 of said tube 8. :Said condensing chamber 5 serves tol condense vapors from :the burning tobacco and to collect .and to 'hold the :same thereby lessening their entrance into the mouth oat the smoker. Said condensing fchaniber 5 serves also :to cool the smoke and to minimize the heating of the mouthpiece of the pipe.

The entire device is simple of construction, being of tew parts, leasily assembled rand easily separated tor cleaning. Preferably the mouthpiece .3, the shell 4, the tube L8 andthe stem 2 of the bowl of the Apipe .are separable each from the other by sliding contacts tted to prevent leakage.

What I ,claim is: Y

l. A tobacco pipe having a condensing chamber, a mouthpiece having an Yinlet passage leading from the outside lair to said chamber, a tube extending across the lower portion oi the lire chamber of the bowl, thence through the condensing chamber and into said inlet air passage in the mouth-- :piece to communicate with the outside air, said tube having a. port .communica-ting with .the lire chamber at or near the bottom of said tire chamber and `so constructed and located that the smoke shall divide to l.enter the tube, said tube having intermediatepits ends a port which rcommunicates -with said condensing chamber, the portion ot the tube on one side of said last mentioned port constituting an air passage and the portion ot' the tube on the other side ot' said port constituting a. smoke passage.

'2. A tobacco pipe having a condensing `chamber through which the smoke and outside air must pass on their Way to the mouthpiece, said condensing chamber being located in the stein portion of the pipe and inclosed by an air-.cooled shell, a tube which passes through said condensing chamber and connnimieates at lone end with the ffire 4chan'feer .oft the pipe and at the other end with .the .(uitsidc air through a passage in the mouthpiece, said 'tube also lcomu]unicating with said condensing .chamber through a. port that divides the tube into la smoke passage and an air passage, said last named port being so located that the air,passage portion of said tube shall extend some distance into said condensing chamber and form an internal condensing member.

8. A tobacco pipe having a mouthpiece connected with the stem of the bowl by va shell that encloses a condensing .chamber through which the smoke and ,outs-ide air must pass on their way to the smoke passage of the mouthpiece, said mouthpiece being formed with a passage into which a tube is fitted to communicate with 4the outside air, said tube extending within said condensing chamber and communicating with it, said passage of the mouthpiece into which said tube is litted ICrm1-mum'.cating with the smoke passage of the mouthpiece through said tube and said condensing chamber.

4. A tobacco pipe having a Iconde-using chamber located in the stem portion of the pipe and inclosed by yan aircooled shell, ,a tube lcommunica,ting at one end with the fire chamber ot the bowl xand passing through said condensing chamber and connecting with a passage lin the mouthpiece communicating with the outside air, 'said tube having a port which 4connnimicates with said condensing chamber and divides the tube into :a -smoke passage and air passage. v

In testimony whereof l affix my signature.
